LIQUID-MEASURING APPARATUS.

4 SPECIFICATION forming part of Letters Patent No. 753,283, dated. Marbh1, 1904.

To all whom it may concern:

Be it known that I, THOMAS EVERETT MATHER, a citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Liquid-Measuring Apparatus; and I do hereby declare the following to be a full,clear, and exact description of theinvention, such as will I enableothers skilled in the art to which it ap.

pertainsto make and use the same.

My present invention has for its object to provide a simple, cheap, andeflicient device for rapidly'measuring liquids; and to this end itconsists of the novel devices and combinations of devices hereinafter'described, and defined in the claims. 7

The invention is illustrated in the accompanying drawings, wherein likecharacters in- 29 dicate like parts throughout the several views.

tank, which communicates through a supplypipe 6 with the receiving endof the pipe 4 outward of the valve 4.

The delivery end of the delivery or discharge ing pipe 4: terminates ina valve-seat 7 in 5 5 which is swiveled an elbow-like'valve 8. Anoscillating delivery pipe or tube 9 communicates with and is carried bythe elbow portions of said valve 8. A valve-actuating rod or arm 10,shown as oftubular form, is also carried by the elbow portion ofthevalve 8 and projects in a diametrically opposite directio'nfrom a tube9. A valve-actuating dog 11 is loosely pivoted on the rod or arm 10, asbest shown in Figs. 4 and 5. Said dog is provided 5 with a weighted arm12, which yieldingly holds the same in a horizontal position. T (Bestshown in Fig. 4.) The dog 11 is free to move in one direction, but isheld against movement in the other direction by cooperating stops 13 and'14; respectively, on the said dog and on said rod 10. The purpose ofthis dog will pres- The valves l and 1' are provided with reverselycurve'd cam-arms 15, with which the dog 11 cooperates .in, a manner tobe set forth in the description of the operation. The valve 4 isprovided with an arm 16, towhich the lower end of a link 17 is pivotallyconnected, as best shown in Fig. 1. Valve-seats 18 and 19 communicate,respec- 8 tively, with the tops of the compartments 1 and 1, and thethree compartments 1, 1", and

1 are in communication at. their tops through an air-tube 20, whichopens at its intermediate portion into said compartment 1 and 5 at itsends into the lower ends of the valveseats 18 and 19. The valve-seats 18and'19 are provided, respectively, with rotary valves "or stop-cocks 21and 22, one of which stands in an open position while the other isclosed, 9 and vice versa. Air-venting pipes 23 and 24,

respectively, lead upward from the valve-cases 18 and 19. The upper endof the ventingpipe 24 opens into an enlarged head 25, provided at itsupper portion with air-holes 26. The bottom of the head 25 is preferablyinclined, as shown in'Fig. 1, and the pipe 24 is provided just abovesaid bot-tom with perforations 27, through which the water may run backfrom said head and said tube. For I9 9 by a chain or other flexibleconnection 30.

dog 33. the dog 33 is gravity-held against a stop-pin racy ofthemeasuring device.

The said tube 9 is also provided with a projecting cam-pin 31, whichacts upon the free end of the arm 28, as will be hereinafter described.The link 17 which is connected to the valve-arm 16, is pivotallyconnected to the valve-arm 29. The said arm 29 is provided with aprojection 32, towhich is pivoted a In the normal positions of the parts34 on the projection 32, as shown in Fig. 1. The oscillatingdelivery-tube is further provided with a second cam-pin 35, which actsupon the arm 29 andupon the dog 33 thereof to oscillate the valve 22 ina manner presently to be described. Stops 36 and 37 on the side of thetank 1 limit the return movements of the valve-arms 28 and 29,respectively.

Operation: Normally the parts stand as shown by full lines in Figs. 1,2, and 3. Directing attention to Fig. 3, it Will be noted that thevalves 4, 4, 4, and 22 are open,

while the valves 8 and 21 are closed. It is evident that in thesepositions of the valves the liquid from the supply-tank 5 will freelyflow into the several compartments 1 1 1 of the measuring-tank 1 andwill fill the same,

since'the air is freely exhausted therefrom through theopen valve 22 andvent-pipe 24. It is also evident that the liquid will risewithin thesaid tube 24 iii-seeking its level Within the supply-tank 5. If fivegallonsto wit, the entire contents of the several compartments of themeasuring-tank 1are to be measured out, the valves 4 and 4 are leftstanding open, with their arms 15 positioned as shown in Fig. 1, and thedelivering-tube 9 is simply oscillated-from its normal position(indicated by full lines in Fig. 1) into the position indicated by.dotted lines in said view and by full lines in Fig. 4. This movement ofthe said delivery-tube, it will be noted by reference to Fig. 4, opensup the valve 8, so

that the liquid will freely runout through the said delivery-tube. Itwill, however, be noted that the said same movement of the deliverytubecauses the cam-pin 35 thereof to engage vthe dog 33, and thereby forcethe valve-arms 16 and 29 into the positions indicated by dotted lines inFig. .1, in which positions the two valves 4 and 22 are closed. Theclosing of the supply-valve 4 cuts ofi the supply of liquid whilethemeasured liquid is being discharged, and the closing of the valve 22prevents the downflow of the liquid contained in the vent-pipe 24, andthus insures the accu- Again, the latter part of the downward movementof the delivery-tube 9 after it has closed the two valves 4 and 24 drawsupon the chain 30 and moves the valve-arm 28 into the position indicatedby dotted lines in Fig. 1, and thereby opens the vent-valve 21. Thus itwill be seen that the liquid will not begin to run from thedelivery-tube 9 until said tube has reached approximately its extremelowered position. After the measuring-tank has been emptied or thepredetermined amount of liquid drawn therefrom the delivery-tube 9 isturned back to its normal position, under which movement its cam-pins 31and 35 .acting, respectively, on the valve-levers 28 and 29, close theventvalve 21 and again open the vent-valve 22. It will of course be seenthat the supply-valve 4" will be opened simultaneously with the openingof the vent-valve 22, since the arms of the said two valves areconnected by the link 17 It will also be understood that the dog 33 willfreely swing under the return movement of the delivery-spout to permitthe cam-pin 35 to pass by the same and into engagement with thevalve-arm 29,. If but one gallon of the liquid is to be measured anddrawn 013?, the valve 4 should be closed before turning down thedelivery-spout 9, while if two gallons are to be drawn OK the valve 4'should be left open and the valve 4 should be closed. The said valvesare closed by hand or by operating the levers 15. When one of the saidvalves is closedfor instance, the valve 4?its lever 15 will stand asindicated by dotted lines in Fig. 1. in which position it stands in thepath of movement of the dog 11. This being the case, when thedelivery-tube 9 is turned downward the said dog swings freely to clearthe same; but as said dog cannot swing in an opposite direction it willwhen the said tube 9 is turned back to normal position engage the saidvalve-lever 15 and cam the same back to normal position and close thevalve. In this way the valves 4 and 4 are always automatically restoredto their normal open positions by the return movement of thedeliverytube.

As is clear from the above description, the valve 22 in the vent-pipe 24is opened up to permit air to be exhausted from the measuring-tank andthe said tank to be filled with the liquid, while thevalve 21 in thevent-pipe 23 is opened up to permit air to flow into the said tank andthe said tank or certain'compartments thereof to be emptied. When air isforced upward through the pipe 24 while the said pipe is filled orpartially filled with liquid, the liquid therein will be caused tobubble up and overflow the upperend ofthe said pipe, but will be caughtby the expanded head 25 and will flow back into the pipe 24 when thevalve 22 is opened.

A liquid-measuring apparatus of this character is capable of a greatmany diflerent uses, but will be found especially serviceable-bygrocerymen and other merchants for measuring and dispensing variousoils, such as kerosene and gasolene, table liquids, such as vinegar, andeven the heavier liquids, such as molasses and syrup.

It will of course be understood that the device is capable ofconsiderable modification as to its details of construction within thescope of my invention, as herein set forth and claimed.
